Ieiic'rs Patent No. 104,959, dated July 5,1870.

IMPROVED IIL'I'ER-SUPPOR'IEE The Schedule referred to in these Letters Patent and making part of the same.

Be it known that-I, FRANK (J. Huelens, of Frank;-

fort, in the county of Franklin and State of Kentucky,

have invented a 'new and improved Filter-Supporter; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same: reference being had to the accompanying drawing forming part of this specification.

. Figure 1 represents a vertical central section of my improved filter-supporter.

Figure 2 is a plan view of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to provide a funnelshaped supporter for filters, whereby the entire surface of the filter will be utilized and the process of filter- The entire surface can, therefore,'be used'for filtering, which will materially hasten, the operation. The

open holder will also leave aehannel for the escape of air from the'bottle or vessel, and will not require the use of. a stick, string, or other device necessary tokeep funnels from closing too tight.

It will be readily perceived that the ribsa are in the shape of broad blades, which, protruding inward, have the efiect to .corrugate the paper, and to bolda large portion of its surface out of contact with every-' thing but the liquid. Thus the filter is not only caused to maintain the desired position, but, being unsupported, eizcept' by edges, it is much better adapted to transfer the percolating fluid through its pores.

Having tbusdesribed my invention,

I elainrasnew and desire to secure by Letters Patent As an. article of .inamiihcture, a filtersupporter, formed-of the large flanged ring, b,'-small conical ring, 0,

and the-series of broad blades'a, all arranged as and for the purpose described; FRANK C. HUGHES.
